(2012-08-30)Maize and sorghum are very important crops in Zimbabwe. They are, however, attacked by several pests, among them stemborers. Host suitability studies using Cotesia flavipes Cameron (Hymenoptera: Braconidae) against Chilo ... -
Assessing the Effectiveness of Soil Solarization for the Control of Soilborne Plant Pathogens and Weeds.
(2012-08-30)A field experiment was carried out at the Department of Crop Science, University of Zimbabwe in the 2003/2004 season to investigate the effectiveness of solarization on the control of soilborne plant pathogens and weeds. ... -
Assessing the genetic value of exotic maize inbred lines and agronomic performance of their corresponding maize single-cross hybrids with the elite CIMMYT lines.
(University of Zimbabwe, 2019-06-01)Exotic germplasm is known to improve productivity and variability of the locally adapted populations, however little has been done to assess gains that could be attained after genetic integrations in the CIMMYT-Zimbabwe ... -
An assessment of the profitability of small holder commercial egg production in Zimbabwe: A case study of Goromonzi, UMP and Mutasa districts
(2016-06)The past few years in Zimbabwe have seen a rise in the number of smallholder farmers taking up commercial poultry production. Past research has also shown that smallholder poultry production suffers from low profitability ... -
Characterisation of Goat production systems and productivity in Rushinga Communal area, Zimbabwe
(2012-07-11)One monitoring and 2 on-farm experimental studies were undertaken using goats that belonged to smallholder farmers in Rushinga communal area, Zimbabwe. The objectives of these studies were to investigate the effect(s) of ... -
Characterisation, Epidemiology and Control of Scab on Protea Spp. Caused by Elsinoe Spp. (Anamorph Sphaceloma Protearum).
(2012-08-30)Protea scab, a commercially important disease of Protea spp., is discernable by raised, circular to oval, red – black leaf and stem lesions, which distort young plant growth. The causal agent was determined to be Sphaceloma ... -
Combining Ability Analysis for Early Maturity and Phaeosphaeria Leaf Spot Resistance in Regional Maize Germplasm
(2012-08-30)Phaeosphaeria leaf spot (P. maydis Henn.) disease has the potential to cause substantial yield losses in maize (Zea mays L,). Maize is grown by smallholder farmers without fungicides; hence the need to breed for resistance ... -
Combining ability and GXE analysis for grain yield performance among CIMMYT germplasm
(2016-06)The International Centre for Maize and Wheat Improvement (CIMMYT) develops inbred lines and hybrids yearly that have several breeding and commercial attributes. However, the recently developed inbred lines that are adapted ... -
Combining ability and heterosis of heat and drought stress tolerance in maize (Zea mays L.).
(2019-05-01)Drought and heat stress are major abiotic stresses limiting maize production in Zimbabwe and Africa at large causing low yields. In order to bridge on this gap of low yields, within its Stress Tolerant Maize for Africa ... -
Combining ability between drought and heat stress tolerant donors and adapted CIMMYT Zimbabwe maize inbred lines
(2016-06)Drought and heat stress are major abiotic stresses limiting maize production in Zimbabwe and Africa at large. It is of great importance to evaluate the breeding value of combined drought and heat stress donor parents for ... -
A comparative analysis of maize technical efficiency between a1 resettlement areas and communal areas in Goromonzi District, Mashonaland East Province
(2013-06-04)ABSTRACT This study sought to establish the differences in technical efficiency levels between A1 and communal farmers in Goromonzi District, Mashonaland East Province. Detailed survey data was obtained from 100 farmers ... -
The contributions of women in farming to the political economy of Zimbabwe: A focus on women in A1 and A2 farming models (2000-2016).
(University of Zimbabwe, 2019-08-01)This study examined the contributions of A1 and A2 black women farmers, who benefitted from Zimbabwe’s Fast Track Land Reform Programme (FTLRP), to the political economy of the country for the period 2000 up to 2016. The ... -
Crop Residue Management and Termite Prevelance Under Conservation Agriculture in Zimbabwe
(2014-04-24)The challenge of maintaining a permanent soil cover using crop residues under conservation agriculture (CA) among smallholder farmers in Zimbabwe is mainly attributed to competing uses such as livestock grazing the residues. ... -
Detection of Tobacco mosaic tobamovirus resistance gene (N-gene) in tobacco genotypes using gene specific markers.
(University of Zimbabwe, 2012-11-01)Tobacco mosaic tobamovirus (TMV) is one of the most destructive viral diseases that threaten worldwide tobacco production. Use of host resistance appears to be the best way to control the disease. The use of specific ... -
Developing a method for the enhancement of the Beta Carotene content of Sweet Potato (cv BRONDAL) using Protoplast Technology
(2012-08-30)Agronomically superior sweet potato (Ipomoea batatas) variety Brondal contains relatively low amounts of vitamin A as opposed to low yielding variety Nemagold, which is relatively rich in high amounts of the nutrient. The ... -
Development of tobacco (Nicotiana Tabaccum) yield estimation models using agronomic and remote sensing techniques
(2016)Farmers need to monitor crop growth and development and obtain early estimates of final yield. The unavailability of a comprehensive method for estimating crop yield leads to contradicting estimates, subjective national ... -
Ecology of maize-cowpea intercropping on biological nitrogen fixation, productivity and grain mineral composition along soil fertility gradients in Zimbabwe.
(University of Zimbabwe, 2019-10-01)Recurrent droughts, infertile soils, lack of adequate machinery and other inputs are jeopardizing crop production in the smallholder farming sector of Sub Saharan Africa. Diversification and intensification of farming ... -
